Right so I posted this in both the kernel thread and the overclock thread but nobody saw it so I'll just post it again:
While looking at the vogue forum, I found a thread about GPU overclocking : http://forum.xda-developers.com/showthread.php?t=697673 the changes made to the kernel to enable this are the following: http://git.linuxtogo.org/?p=groups/...ff;h=23ff83048726252bc785699fc749a3e364a3bdb0
Unfortunately I am no programmer and I do not see how to incorporate this code in to kernel sources for MSM7xxxA processors, though it should probably work because the gpus of A and non-A processors are pretty much the same (same basic specs such as number of triangles etc.), so if a kernel dev. could try to integrate this patch, that would be awesome.
this really looks like some awesome stuff! i hope someone can figure this out for the g1. thanks for supporting the g1 thread!
GPU overclocking
Holy crap, a dev should take a look at that source NOW
agreeeeed^
just saw this thread for the first time.
gona take a look
Even though its a good idea in theory..
Once you start over clocking the GOS you really gona kill not only battery life, but your phone will be able to cook eggs lol
Thanks kingklick, hopefully you'll figure it out so we can run newer 3D games better, as for overheating, dzo (who created this modification) says that he hasn't noticed anything differences in temperature after overclocking the GPU on the Vogue
It will be cool if someone can overclock the GPU , these days everybody is talking about overclocking the cpu , but what allot of people do when they are traveling is playing games, some games we cant play because they are a little bit to heavy for the GPU. Kingklick thanks for looking at this topic,
personally I have really much confidence in you!
For this to work.
Someone has to implement this for MSM72XX, which is completely different than what's in the TI phones.
I am not sure if that code is even in the kernel (GPU clock). I don't recall seeing it but I haven't really looked at the kernel all that much.
It's all in the board files if it's anywhere.
/arch/arm/mach-msm/
Are you sure it's safe to OC the GPU?
It's not like we're using a adreno or Power VR in these phones. Also doesn't android use the CPU for things like scrolling,animations,swiping,etc...

Um, the HTC Vogue (or Touch CDMA) AFAIK uses the Qualcomm MSM7500 which pretty much has the same GPU, just clocked slower than in the MSM7XXXA series, so I think it's just a case of recoding the modifications made by dzo (android kernel developer for the Vogue) for other phones.
The GPU code for the MSM chips is in /drivers/video/msm/gpu/kgsl/
I haven't looked at any of the code much, but kgsl.h defines some structs for what I think are clock values and in kgsl.c it contains:
Code:
/* the hw and clk enable/disable funcs must be either called from softirq or
* with mutex held */
static void kgsl_clk_enable(void)
{
clk_set_rate(kgsl_driver.ebi1_clk, 128000000);
clk_enable(kgsl_driver.imem_clk);
clk_enable(kgsl_driver.grp_clk);
}
Which to me looks a lot like its setting the GPU clock at 128Mhz.
Just my $.02

I modified this on the Eris's kernel to 160000000 and ended up with slower benchmark scores in both Neocore and Quadrant. So... possibly not that.

Can you try others like:
352x
480x
176x

384 gave me close to normal speeds but still slower than 128... 160 was slower.
It doesn't make sense.
If overclocking the GPU is anything similar to the CPU, then shouldn't we be using multiples of 19.2? instead of 128, try 147.2 or 176.4 etc....

But the stock is set to 128, which is not a multiple of 19.2.
If messing with it caused the phone to go slower, then it must be possible to mess with it to make it go faster.
dzo, linked me to his commit and it doesn't correspond to anything in the eris source.

Time to poke around...
Owning both a Kaiser and a G1, the Kaisers 3D is actually faster. A lot of apps render quicker and smoother. Games play better too.
Would be nice if someone could pick this up, and get some over clocking action going for the GPU. Even without the overclock, my Kaisers GPU seems so much faster, but yet it's a weaker GPU then what my G1 has.
So I rooted my Droid X2 and installed Set CPU. I had problems running set CPU, I couldn't use the drop down menu for setting CPU governors, I also couldn't over clock my CPU, just under clock. Does set CPU work with the nvidia tegra 2 dual core processor in the X2? If not, which app will let me overclock and change CPU governors?
You have to have a custom kernel that allows overclocking.

I'm really new to Android, i've been using iOS for years, and finally jumped the fence. I just rooted my Droid X2, used Titanium Backup Pro to freeze all the bloated apps, and I wanted to get more control of my CPU, as well as overclock a little. I thought I could just install SetCPU and I would be able to Overclock.
So in order to have a custom kernel I would have to install a custom ROM? Such as Cyanogenmod? As I said, I am pretty new to Android, but if I am correct, Cyanogenmod is not available yet for the Droid X2 is it? Are there any other custom ROMs that are available or would work with my X2?
Is it really even all that necessary to overclock what is already a pretty powerful device? Nvidia Tegra 2 dual-core processor is powerful in its stock form isn't it? I would almost think I would gain more by dialing the CPU down at certain times, at least I would gain battery life. I think I am able to set up profiles with SetCPU without having a custom kernel, right?
This is a useless app made by Vietnamese people (I'm Vietnamese). It cannot overclock which many people mistakenly believe, and it only has the task of limiting the CPU speed, the CPU speed is managed by the OS and limiting it is a bad way because no matter what task it does it will be slowed down. When idle the CPU will automatically reduce its voltage and speed by OS. Any process no matter how big or small with high CPU speed it will be processed very fast even with small tasks that are reported not to use up CPU but it will still be faster than a slower CPU. Kernel Auditor is also useless.
it's not you install a custom kernel to manage cpu to overclock by some app but you're going to overclock into kernel using a custom kernel
OK guys. After much searching i've just become confused as to which is the best overclock app/ROM for the HTC sensation z710e. I used SetCPU but it couldn't actually take my processors above 1.188GHZ and I tried the sense-o-maniac ROM and also the android revolution 6.0.3 ROM, both of which say the processors are overclocked to 1.5GHZ but there is absolutely no difference to me, no they are not slower, and I just want a clear straight up ROM or app that OVERclocks.
Thanks,
Sensation lover
I under clocked my cpu to 1 ghz and I see no difference in speed.... From 1.2 to 1.5 its 20% increase in cpu speed.... Speed of the phone doesn't depend on cpu alone... So thats around 7-10% increase in speed overall (because there is gpu, ROM, sd card, memory)... And thats maybe... Do you really think you can see 7% in speed? Try some synthetic cpu benchmark with 1.2 and 1.5 and only then will you see....
This is my five cents ;-)

Well the app that controls the CPU clocking is limited in what it can do by the Kernel you're running.
If you're Kernel only supports 1.18 Ghz, Set CPU can't do anything about it.
So you need a Kernel that supports overclocking. The Kernel also controls what kind of governors who can put on the CPU (Conservative, performance, battery saving, etc...)
As far as the controller apps go though, I like the ones that can set the screen off speeds at a different rate than the screen on speeds. That makes sure I don't drain battery at alarming rates when the phone is in my pocket because a rogue app decided it wanted to get funky.
As Skipjacks mentioned, the overclocking speed is due to the kernel you have flashed.
If you are unsure on which kernel to use,
Always use the kernels suggested by the ROM developer.
Of course, you could try various Kernels but do keep in mind that not all ROM's support different kernels.
Normally the current roms has CPU clocking apps built into it,
one widely used is the Daemon control. It usually comes with an app that you can control the overclocking speed.
The current app i'm using, I use System Tuner Pro (yes I support app developers)
It enables me to force cpu2 online, which ultimately makes my phone faster.
Hi!
I'm looking for a kernel that supports both CPU+GPU overclock.
I almost have already visited most of the kernel, but did not find GPU overclocking, do not nobody care about this issue?
In addition to Zeus Kernel 4.0, he did not support my machine is N8000, so I do not mind losing 3G capabilities, because I do not have to, but after trying it did not find GPU overclock control.
So people know about GPU overclocking in N8000 do?
Software I already have, I only need the kernel.
Thanks!
Hi
I own SM-P900 and using Lineage OS. I would like to boost the cpu and gpu as much as possible. Can someone give me some good numbers for voltages/freqs that I could input in apps like Kernel Adiutor?
thanks
Not sure you can even overclock our CPU. If you could do it, I would be worried about heat issues.
